In vitro acaricidal effect of Melia azedarach ripe fruit extract against Dermanyssus gallinae (Acari: Dermanyssidae)

The aim of this study was to evaluate acaricidal activity of Melia azedarach L. ripe fruit extract against Dermanyssus gallinae (De Geer, 1778) under laboratory conditions. For this purpose, hexanic ripe fruit extract of this tree at concentrations 0.25, 0.5, 1, 3, 5 and 10% were prepared with acetone as solvent and treatment groups exposed to these concentrations using Petri dish residual film bioassay method. The positive control was carbaryl while negative control was acetone. The bioassay was repeated five times. The mortality rate of mites in treatment and control groups were assessed 24 h post exposure. All treatment groups showed significantly higher mortality compared to the negative control group (P
